As duty-cycle-dependent intervals, CENTINEL removes a small amount of used oil and sends it to your fuel tank. The used oil blends with the fuel and is burned during combustion. Simultaneously, CENTINEL adds the same amount of new oil from a makeup tank into you engine. This constantly replenishes oil additives, improving oil quality over the life of your engine. With the required Fleetguard ES System oil and fuel filters, the heavy-duty automotive oil change interval extends to 525,000 miles, with oil filter change intervals at 100, 000 miles. In High-horsepower industrial applications, the oil change interval is 4,000 hours and the oil change interval is 1,000 hours, minimizing waste-handeling and disposal costs.
